What is the main use of hydroxyacids in chemical peels?

• A. Moisturization
• B. Keratinolysis
• C. Sun protection
• D. Deep tissue healing

Answer: (B)

Hydroxyacids, particularly alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), are primarily utilized in chemical peels for their ability to promote keratinolysis, which is the breakdown of keratin in the skin. This action facilitates the exfoliation of the epidermis, leading to the removal of dead skin cells, improved skin texture, and enhanced cellular turnover. By promoting keratinolysis, hydroxyacids help in the treatment of various skin conditions, including acne, hyperpigmentation, and signs of aging, giving the skin a smoother and more radiant appearance. While hydroxyacids may also impart some level of hydration—due to their humectant properties—and have a role in certain aspects of skin healing, their primary and most significant benefit in the context of chemical peels is their exfoliative effect through keratinolysis. Other options such as sun protection and deep tissue healing are not direct uses of hydroxyacids in chemical peels and do not capture the principal effect that these acids have on the skin.
